How Temporal Powers Reliable Cloud Operations at Netflix

This post explains how Netflix adopted Temporal, a durable execution platform, to improve reliability of cloud operations in their Spinnaker CD pipeline.

• •Netflix reduced transient deployment failures from 4% to 0.0001% after migrating Clouddriver's cloud operation execution to Temporal.
• •The original Clouddriver system suffered from instance-local task state loss on crashes, complex custom retry logic, a homegrown Saga framework, and tight coupling with Orca's polling mechanism.
• •Temporal organizes business logic into deterministic Workflows composed of Activities, with the server durably storing execution state to survive crashes and transient failures.
• •Cloud Operations previously decomposed into AtomicOperations are now expressed as Temporal Workflows, eliminating the need for Clouddriver's internal orchestration engine.
